To all whom it may concern: A the set screws 3 carried by the collars andv Be it known that I, FRANK ROBERTS, a adapted for engagement against the bar l. citizen of the United States, residing at The collars .2 are carried by the channel Chicago, in the county of Cook and State of bar fl and are secured to the side of the Illinois, have invented certain new and nselatter to hold said channel bar to one side 60 ful Improvements in Printing-Press Attachof, and parallel with the stick 1. The parinents; and l do hereby declare the folloW- allel sides 5 of the channel bar-4 are coning to be a full, clear, and exact description nec/ted at their ,opposite ends by the pins 6 of the invention, such as will enable others and the ends of said sides preferably proskilled in the ai't to which it appertains to jectbeyond the ends of the bottom portion 65 make and use the same. of the channel bar 4, and are rounded as This invention relates to printing pre-ssV will vbe clearly understood. attachments and more particularly to an at- Piiyoted to one of the pins 6 is the link 7 tachment for the liy fingers of a printing whic is adapted to swing upon the pins y6 press. for a limited distance, movement of said link 70.

An object of the invention is to provide, an being limited' by a stop 8 having its oppoattachment for the fly fingers which will notsiie ends secured to the parallel. sides 5, only assist in depositing the printed sheets above the..pi.ns 6 and extending transversely upon the -fly board but will prevent said of the channel bar 4, said stop S being resheets from rising as the fly fingers swing ceived in the cutaway port-ions 9 of-the end 75 upwardly to return to their initial position of said link. The opposite end of the link to receive the next sheet. y 7 carries a rivet or pin l0 upon which is also Another object is to provide an attachmounted one end of a second link 7, said end ment of this character which may be apbeing also provided with cutaway portions plied to printing presses of various char- 9 to accommodate the movement limiting 80 acters and which will save time, labor and stop'S carried in the outer ends of the first expense by. preventing the printed sheets link 7. It will be understood that the seefrom moving after being deposited upon the ond link 7 is slightly shorter than the first fly board and also prevent the corners of the link 7 and is adapted to rest within the rst sheets from becoming bent or otherwise inlink when the attachment is in closed posi- 85 jured. tion, as will be later more clearly under- Other objects and advantages will be stood. hereinafter set forth in the specification and A numberof links 7 are provided, each Claims, linkl having its inner end mounted upon the Referring to the drawings which are made rivet carried by the outer end of the link 90 a part of this application, Figure 1 is a by which the outer link is carried, each sucfragment-ary side view of an ordinary ily ceeding link being slightly shorter than the finger of a printing press with my attachlink before the same and adapted to rest ment secured thereto, showing thelatter within the longer link by which it is carin open position.l Fig. 2 is a` plan View at ried. The movement of each link 7 is lim- 95 right angles to Fig. 1, the opposite ends ited by providing the stop 8 and cutaway of the fly finger being broken away.

During the latter part of this movement'of the fly fingers 1, the links 7 Hy out of the channel bar 4, and the button 11 forces the paper upon the Hy board and remains in engagement with the paper until after the Hy fingers have started upon their return to their normal position, said button holding the printed sheet in position upon the Hy board and preventing the same from returning with the Hy fingers 1. During the latter part of the return movement of the finger bars 1, the button 11 raises from engagement with the paper upon the Hy board and the links 7 return to their normal positions Within the channel bar 4, the button 11 resting upon the links'7 and upon thesides 5.of the channel bar 4.

If it is desired to discontinue the use Fof the attachment, the same may be rendered inoperative by removing the thumb screw 14 from its position within the ends of the sides 5 and passing said screw through the openings 15 provi ed therefor through the links 7 and the sides 5, as will be clearly understood,

It will thus be seen that I have provided an attachment for'a printing press which will prevent printed sheets from leaving the Hy board after having once been placed thereon by the Hy4 fingers 1 of the machine and which will also prevent bending and tearing of thecorners ofthe sheets.v

It will further be evident that the attachment may be applied to the fingers ,l so as to engage the paper in the margin and thus eliminate all danger of blurring the printed face of the paper.

It will further beevident that this attachment will save not onl a large amount of timel and labor but will7 also greatly diminish or decrease the loss of stock, ink, etc., heretofore experienced by printing establishments.

What I claim is 1. .An attachment for a Hy stick comprising a channel bar, means for securing the channel bar to the Hy stick, links carried by the `channel bar and adapted to normally rest within the latter and a paper engaging button carried by said links.

2. An attachment for a printing press comprising a channel bar, connected links, each link being carried by a longer link, means for limiting the movement of each link in relation to the link by which it is carried, the longest link being secured in the channel bar, said links being adapted to normally rest within the channel bar, and a paper engaging button carried by the:

shortest lin 3. AAn attachment for a printing press Hy finger-comprising a channel bar, collars carried by the channel bar for engagement around the Hy finger, means for securing the collars in position around the Hy finger, links connected to one another, one of said links being connected to the channel bar, said links being adapted to fit within one another and normallyv rest within the chan,

nel bar, a paper engaging member pivoted to one of the links, 4and means for locking the links in position within'the channel bar.

In testimony whereof I .have signed my name to this specification in the presence of two subscribing witnesses.
